Felt filter socks give the best qualities of trapping free floating debris to give your tanks water that crystal clear appearance.  Felt filter socks with the plastic rings make replacement quick and easy, and most sumps will readily accept the BRS felt filter sock.  In most cases we will always put felt filter socks in our sumps.

Filter Socks are used on overflows to remove small floating particles from aquarium water. This can dramatically improve water quality and reduce maintenance on filters that would otherwise become clogged.

Felt Filter Sock is better at removing particles than mesh but can clog faster. The plastic ring fits common sump holders.
